General building lighting – high pressure sodium and metal halide discharge lights are suitable for high ceiling areas. Use metal halide discharge lights to give the best colour rendering and a natural white light. You might also consider newer high output LED lighting.

Local lighting – use local strip lighting in areas where high visibility is needed for work over equipment like grading machines. Choose units with electronic starters and thinner, high efficiency tubes. Where accurate colour rendering is important, use natural daylight tubes.

Natural light – clear panel roof sections will provide natural light in daylight hours, but make sure the panels are kept clean or else they will become ineffective. Link dimmable fluorescent lighting to a light sensor to reduce the output of artificial light as natural daylight increases.

Lighting on demand – clever proximity control lighting on large buildings can help to light work areas as and when needed – so as someone walks or drives a fork lift through the building, the area where they’re working is lit for a short period.

Car park lights – replace tungsten halogen lamps with high pressure sodium, metal halide discharge lights or newer high output LED lighting. Control the lights with timers or, in the case of LED, movement sensors. Your running costs will be reduced by 75%2

2 Choosing modern LED’s over Tungsten Halogen lights will use less than a quarter of the energy. Using a 7W LED instead of a 35W tungsten bulb will save 80% (7W / 35W x 100 = 20%) (For more information on lighting, see, Carbon Trust: Display Lighting).
